This application is a continuation in part of my co-pending application,Serial No. 329,623, filed April 15, 1940.

The invention relates to cocky molding machines, and more particularlyto such machines of the rotary type wherein cookies are formed in thedie cavities of a continuously rotating cylindrical die roll.

Cocky machines of this character are customarily used in large bakingplants where cookies of a particular design or form are molded by themachine at a rapid production rate and are deposited by the machine ontoconveyor-carried pans, or directly onto a steel band conveyor so as tobe advanced through a continuous type baking oven.

Such machines, in a general sense, embody a hopper for receiving thedough which passes therefrom into the space between opposed forcing anddie rolls which form the bottom of the hopper. The die roll and theforcing roll are driven in unison in opposite directions so that thecocky die cavities in the die roll are filled with dough which iscompressed in the die cavities so as to properly form the cocky blanks.In the continued rotation of the die roll, the excess dough is trimmedfrom the exposed face of the cocky blanks, and the cocky blanks are thenextracted from the die cavities. This extraction is usually attained bymeans including a fabric belt which delivers the cocky blanks to theoven conveyor or the pans.

Since such machines have a very high production rate, often exceedingone million cookies in an eight hour day, it is necessary to change thedie roll several times during a working day so as to limit theproduction of each cooky design to a reasonable amount. In view of thesefrequent changes, an important object of the; present invention is toprovide a new and improved cocky molding machine wherein the changing ofthe die roll is simplified and requires less time than in priormachines, thereby to reduce the idle time of the machine and of the ovenwith which it is normally associated or used.

A further object is to provide such a machine wherein the danger ofdamaging the die rolls during the roll changing operation is minimized.

In the extraction means of such cocky machines the fabric belt ispressed against the exposed faces of the cookie blanks by means of arubber covered pressure roll. This rubber roll is formed by means of arubber sleeve or sheath surrounding and fixed upon a steel core or shaftwhich provides the rotatable bearings for the rubber roll. Since thecocky dough contains a relatively high percentage of shortening which isexpressed from the dough at various stages of the molding operation, andsincethe belt is normally well soaked in such shortening to attainbetter extraction, it is found. that such shortening accumulates on therubber roll; and While the rubber itself may be selected to resist thedeteriorating action of the shortening, it is found that such shorteninggathers also on-the ends of the rubber roll, so as to work into theannular joint formed between the rubber sleeve and its steel core. Thisentry of the grease or shortening loosens the end portions of the rubbersleeve from the supporting core, and this result is detrimental since itreduces the extracting efiiciency of the machine.

Another object of the present invention is, therefore, to reduce thefailures of the extracting means by providing a cocky molding machinewherein the ends of the rubber roll are so positioned that the operatorsmay easily remove the grease or shortening from the ends of the roll andthereby prevent loosening of the rubber sleeve or coating thereof.

Cocky molding machines of this character are used in bakeries where theconveyor type oven often has a relatively large biscuit and crackercutting machine permanently associated with the intake end of the oven,and another object of the present invention is to provide a cookymolding machine adapted for association with such a permanently mountedcutting machine so as to deliver the molded cookies to the ovenconveyor.

A further object is to provide such a cocky molding machine wherein allof the operating parts are located above the level at which the cookiesare finally delivered by the extraction belt, thereby to particularlyadapt the molding machine of the present invention for mounting on andoperative association with the standard cutting machine base.

A further object is to provide such a cocky molding machine wherein allof the operating parts are located above said delivery level and whichavoids undue height of the machine.

A further object is to provide a machine of this character wherein thedelivery belt or extraction belt may be released or slackened in acomparatively simple manner. I

A further object'is: to provide such a cocky molding machine wherein thetightening means for the extraction belt acts upon said belt at a pointrelatively close to the cocky molding roll.

Another object is to provide such a cooky molding machine wherein thereplacement of the extraction belt may be attained in a relativelysimple manner.

Another object is to provide such a cooky molding machine wherein theextraction belt at the point of delivery of the cookies to the conveyoris relatively rigid in the sense that it is at all times positioned withits leading edge or delivery edge at right angles to the path of travelof the conveyor.

A further object of the invention is to provide such a cookie moldingmachine having an improved mounting for the hopper whereby replacementor changing of the cooky die roll is simplified and facilitated.

A further object is to provide a cooky machine of this characterembodying new and improved" means for scraping excess dough from the dieroll so as to properly form; the outer or bottom surfaces of the cookyblanks prior to their extraction from the die cavities.

Other objects and advantages will become apparent from the followingdescription, taken in connection with the accompanying drawings, inwhich:

The scope .of the-inventioniwill'be defined by;the appended claims.-'

In' the formchosen for disclosure in Figs, 1 to 5' ofthe drawings,theinvention; is" embodied in a cooky molding 'rnachinelfl. oftheattachment ty e, adapted to be mounted on any suitable base, suchas'the'basell of a conventional cracker cutting machine. Such a crackercutting machine is normally mounted in apermanent relationship to anovenI2 of the continuous type so that a conveyor belt] I 3 extends throughto the basejl I. of the cutting machine and through the oven l2. Thusthe various articles to be baked are formed and disposed on the conveyorI3 and are moved through the oven so as to be baked and are thendischarged at the other end of the oven by the conveyor.

The cooky molding machine ID of the present invention is adapted to bemounted on the upper surface M of the side rails l5 of the frame II, theside rails 15 being disposed on opposite sides of the upper run of theconveyor l3. The cooky molding machine I0 is so constructed that all ofits operating parts are disposed above the level of the surface It. Tothis end the machine I!) has a pair of side frames l6 suitably connectedtogether by means which includes a transverse member IT, and these sideframe members Iii are clamped on to the surface I4 of the side rails l5by means of headed studs IS.

The side frame members l6 serve to support the various operating membersof the present invention there being a cylindrical die roll l9 and aforcing roll 23 of conventional form disposed on parallel transverseaxes with a hopper 2i overlying the exposed upper faces of the rolls I9and 20 so that when the two rolls are operated in unison in oppositedirections by means such as drive gears 22 and 23 the dough in thehopper 2| is forced into the cooky molding die cavities 24 of the dieroll [9.

In molding the cookies the adjacent or exposed surfaces of the rolls [9and 20 move downwardly as indicated by the arrows in the drawings andthe excess dough on the exposed faces of the molded cooky blanks isremoved by means of a conventional spring steel knife mounted on orforming a part of the transverse member ll. As these cooky blanks movewith the roll 19 toward the right and upwardly in Fig. 3, the blanks arecontacted by the surface of an endless extracting belt 25 to which thecookies 26 adhere so as to be withdrawn from the die cavities in whichthey have been molded or formed. The delivery belt 25 extends to theright in Figs. 1 to 3 and downwardly about a nose plate 21 which has afairly sharp forward edge 28 and the cookies therefore fall in aknown'manner from the belt-25 on tothe conveyor 13 by .which tion of these tworolls, and the gears may be drivenby any conventional means.- In theevent ,thatthe cooky-moldingattachment Ill ismpunted on-a conventionalcracker a cutting or like machine, the two rolls l9 and-2B may be drivenina known manner by suitable speed reducing and drive chain-means-fromthe usual power means 29-ml0unted in the base! I.

. In accordance with the present invention the cooky molding roll 19has;a cent-ral shaft 3!] upon which the drive gear 22 is fixed atoneend, and the projecting ends of this shaft .30 provide trunnions 3|which. are adapted to rest'in suitable'bearings in the side frames l6.Theforcing roll 2|] has 'a' similar central shaft'32 having itsprojecting ends arranged to fornr supporting trunnions; These supportingor trunnionlike ends of the shaft 32 of the forcing roll 20 ar esupported in similar bearings 33 formed along the. upper: ed e. of th sdeframes a jac nt t left-hand end thereof as herein shown. The

lower half 33 of each bearing is formed in the upper face of its sideframe it while the upper half 33 of each. bearing 33 is separatelyformed and is removably secured in place by a plurality of headed studs34. The height of the bearing 33' above the mounting face [4 is soproportioned that the lower face of the roll 29 is relatively close tothe surface I4, or more exactly stated, is relatively close to the upperrun of the conveyor The molding roll 24 is supported on an aXis which isat the same height as the axis of the forcing roll 29, and such supportis, in accordance with the present invention, provided by readilyseparable bearings 35 which are so disposed as to facilitate the removaland replacement of the die roll I9. Thus it will be seen that eachbearing 35 comprises a lower fixed portion 35 and an upper separableportion 35", the lower portion being formed as a part of the side frame16 and theupper portion being separately' formed. In accordance with thepresent invention a portion of the bearing 35" is pivotally related tothe side frame so that when the bearing is released, the upper portionmay be pivoted to an out-of-the-way position. As best shown in Figs. 1and 3, the upper and lower portions of the bearing 35 are separable in aplane which is disposed at substantially 30 to the horizontal so that inremoving the die roll from the bearings, the die roll may be movedupwardly and slightly to the right as herein shown. The upper section ofthe bearing 35 is therefore pivoted on an aXis lying in said plane'parallel to the axis of the bearing and on the left-hand side of thebearing axis. On the right-hand side of the bearing aids the upperbearing section 35 has a clamping flange 3'! adapted to be secured tothe frame by headed studs 38 so as to clamp the bearing tightly aboutthe trunnion 3| of the die roll. After the studs 38 have been removed,the upper section of the bearing may be pivoted about its axis from theclosed or operative position'of Fig. 3 to the upper or released positionof Fig. 1. It will be noted that the shaft 30 of the molding roll has aportion 39 extending beyond the trunnioned portion to facilitate liftingof the die roll, and. such a portion 39 is provided on both ends of theshaft 3i].

The hopper 2| comprises two segmentally formed end plates 49 which inthe normal position of the hopper as shown in Fig. 3 bear against theend edges of the upper portions of the rolls l9 and 29. At itsright-hand or forward face the hopper has a forward wall 4| connectingthe two side plates 39, and thi forward wall 6| in the normal positionof the hopper has its lower edge 42 positioned relatively close to theupper face of the die roll I 9 and substantially in the vertical planepassing through the axis of the die roll. At its other edge or rear edgethe hopper has a vertical wall 43 connecting the two side plates and inaddition has a bottom plate 44 connecting the side plates and extendingfrom the rear wall 43 to a point relatively close to th upper surface ofthe forcing roll 20. I

When the die roll I9 is to be removed the hopper 2| must be moved'to anout-of-the-way position, since in its operative position it is locatedin close association with and partially overlying the. die roll l9. Inaccordance with the present invention the hopper 2| is so mounted'andrelated-to. the frame of the machine it that such shifting of the hopper2! to an out-of-the-way position is: facilitated To this end. the hopperend plates 5% are formed with arcuate bearing portions 45- which restagainst an arcuate bearing surface 56 which projects inwardly from theupper and lower portions of each bearing 33. This relationship is shownin Figs. 3 and 5. It will be noted that when the hopper is in itsupright or normal position of Fig. 3, a lower portion 45 of the arcuatebearing surface engages the lower part of the bearing surface 46, sothat by engagement of these two surfaces the hopper is held againstupward movement and also against movement to the left in Fig. 3. Thisinterlocked bearing relationship is utilized in simplifying the securingmeans whereby the hopper is held in its operative upright position, andin addition the relation of the bearing surfaces also simplifies theshifting of the hopper to its inoperative or out-of-the-way position.The hopper is further secured in place by means of angle brackets 41secured to the end plates 40 so that when the hopper is in the desiredupright position, one leg 53 of each bracket bears upon the uppersurface of the side frame l6 between the two bearings 33 and 35. When itis desired to secure the hopper in position a headed stud so is extendedthrough the arm 48 of each angle bracket and is threaded into the sideframe it.

When the hopper is to be moved to an out of-the-way position, the studs49 are removed and the hopper is rocked to the left to the position ofFig. 1 about the bearing surfaces 45 and 4%. Thus the hopper is releasedand moved to an out-of-the-way position in a simple manner, and it willbe evident that its return to its operative position is relativelysimple since the bearing surfaces 55 and 46 act to guide it in itsmovement.

The extracting belt 25 is pressed against the die roll i9 by resilientmeans such as a rubber covered roll 59 which is in many instances termedthe extracting roll. This roll 59 is preferably relatively large indiameter and comprises a me tallic core 5| having an axial shaft withprojecting end bearings 52, and the core 5! has a rubber coating 53thereon. The rubber roll is supported so that it opposes the die roll I9 slightly below a horizontal plane passing through the axis of the dieroll. The extracting belt is, of course, extended from the nose plate 21to the left beneath the rubber roll 50 and between the rubber roll andthe die roll so as to extend over an elevated tightening or idler roll5'5 which is supported above the rubber roll and in spaced relation tothe die roll. From the idler roll 55 the upper run of the belt 25extends to the right over the nose plate 21. I

The rubber roll 59 is supported, in accordance with the presentinvention, as low as possible while yet maintaining the lower face ofthe roll in spaced relation to the surface M and the conveyor it. Therubber roll 50 is also supported for movement toward and away from thedie roll I9 so that the pressure of the rubber roll against the die rollmay be adjusted to produce the op- Movement of the bearingmeans ofscrews 60 to the right-hand ends of the side frames I6. Each bearingblock 56 is held down upon the surface 51 by means of a top plate 6|,and in the form of the invention disclosed in Figs. 1 t one end of thistopplate BI is secured to the top of the end member 59 by screws 62 andthe other end of which is held down upon the top of the side frame I6 tothe left of the face 58 by means of screws 63.

To press the rubber roll against the die roll, suitable adjusting meansis provided for the blocks 56, and in the present instance thisadjusting means comprises, for each bearing block, an adjusting ortightening screw 64 extending through a nut 65 fixed in the end member59 of the bearing. The adjusting screw extends perpendicular to the axisof the rubber roll 50 and on its outer end has an operating handle 66.An inner or left-hand end has a reduced rounded portion 61 engaging acorresponding socket in the end of the bearing block 56 so that thebearing block may be moved to the left by operation of the screw,thereby to force the rubber roll against the die roll 19. The block 55,however, is disengageably related to the end 61 so that the bearingblocks 56 and the rubber roll may be lifted from the bearing surfaces 51when the top members GI are removed. Such removal is required when a newextracting belt 25 is to be put in place on the machine, the mostdesirable of such extracting belts being made in an endless form ratherthan being fastened together on the machine.

If it is desired to have the adjusting screws 64 function also towithdraw the bearing blocks 56, an under-cut or T-slot may be formedvertically in the right-hand ends of the blocks 56, and a correspondinghead may be formed on the lefthand ends of the screws 64 to engage suchT- slots. The bearing blocks 55 would in such a case be easilyreleasable from the screws 64 by vertical lifting of the blocks 55.

The nose plate 21, in accordance with the present invention, is mountedat a fixed spacing with relationto the side frames, I6; and the desiredtightening of the belt 25 is attained through movement'of the idler roll55; The mounting of the nose plate 21 is attained in the present instance by means of a pair of arms HI, each of which is fixed permanentlyto the nose plate 21. The arms 'IIJfare disposed at oppositeends of thenose. plate 21, and extend to the side frames I6 parallel to'the sideedges of the extracting belt 25. The left-hand ends of the arms "I0 aresecured to the inner faces of the 'side' frames I6 by pivot pins .TIwhich are co-axial. Thus the nose plate may be pivoted upwardly aboutthe pivot pins II and .if desired such movement of the nose plate" maybe utilized in.- loosening the belt in connection with the removal of adie roll as will hereinafter be explained. Q'Wheri the extracting belt25 is driven, by its contact with the die'roll I9, the movement of thebelt serves to hold the pivoted arm'sand the nose plate 21 downwardlyandrelatively close to the conveyor I3. Ifdesired a suitable. stop meansmay be provided on the noseplate 21 for engagement with the surface I4,thus to limit the downward movement .of they nose plate .27 by the belt25, and avoid undue stress on the belt. T

'The present invention so mounts the idler roll 55' that it may bereadily moved to an o'ut-of-theway position whenfa. die roll is toberemovedand this mounting is such "as to. providefor convenientshifting of lithe idler roll. 55 to. tighten. the

extracting belt 25. As herein shown, in both embodiments of theinvention, a pair of forked mounting members I2 are provided to engagethe projecting end trunnions 13' of the idler roller 55. In the formshown in Figs. 1 to 3, each forked bearing I2 has a threaded stem I3which projects into a supporting socket I4, and as shown in Figs. 1 to3, this supporting socket is secured as by means of the screws 62 on.-the top of the member BI and directly above the end member 59. From thispoint of support the socket of the embodiment of Figs. 1 to 3 is sodisposed that its central axis extends upwardly at an angle of about 30and to the left. A tightening nut is threaded on each screw shank I3 soas to limit the movement of the shanks I3 into the socket I4. Thus bymanipulation of the nut I5 with relation to the screw shank I3 the axialposition of the shank I3 may be adjusted. Such adjustment is upwardlyand to the left in Fig. 3, so that by adjustment of the two nuts I5 thebelt 25 may be tightened. When the die roll is to be removed the nuts I5may be manipulated to withdraw the forked bearings I2 to the right,thereby to loosen the belt and permit the idler roll 55 to be removedfrom the bearing I2 to the out-of-the-way position such as that shown inFig. 1. Such loosening of the belt 25 may also be attained by upwardpivoting of the nose plate 21 as heretofore explained.

In the alternative construction illustrated in Figs. 6 to 10, inclusive,the invention is embodied in a cooky molding machine III) adapted for association with the base II of a conventional cracker cutting machine orthe like in the same general manner as the machine II] of Figs. 1 to 5,so that cooky blanks molded by the machine I I0 may be discharged in thesame manner upon pans or upon a conveyor I3.

The cooky molding machine III] of Figs. 6 to 10, inclusive, is similarlyadapted to be mounted on the upper surface I4 of the side rails I5 ofthe frame II, and the cooky molding machine III] is so constructed thatall of its operating parts are disposed above the level of the surface II. 'Similarside frames IIB are secured onto the-surface I4 ofthe siderails I5 by means of'headed studs II8. Y

The side'frame members I I6 serve to support the various operatingmembers of the present invention in the same general manner as in theother embodiment, there being a cylindrical die roll H9 and a forcingroll I of conventional form disposed on parallel transverse axes with ahopper I2I overlying portions of the exposed upper faces of the rolls H9and I20 so that when the two rolls are operated in unisonin oppositedirections by means such as drive gears I22 andI23 the dough in thehopper-I 2I is forced into the cooky molding die cavities I24 of the dieroll H9. I Excess doughon the exposed faces of the molded cooky blanksisremoved by means of knife means mounted in thespace beneath theadjacent lower surfaces of the rolls II9 and I20, and in accordance withthe present invention this knife means is arranged to withstand shockright .inFigs. 6 and 'ZZandi downwardly abouts.

nose plate I21 which has a fairly sharp forward edge I28 and the cookiestherefore fall in a known manner from the belt I25 onto the conveyor I3or other means by which they are then moved through the oven.

The gears I22 and I23 of rolls III! and I25 are intermeshed so was toproduce the desired rotation of these two rolls, and the gears may bedriven by any conventional means, such as that described in connectionwith Fig. 2.

The cooky molding roll II9 has a central shaft I50 upon which the drivegear I22 is fixed at one end, and the projecting ends of this shaft I30provide trunn-ions I3I which are adapted to rest in suitable bearings inthe side frames I 15. The forcing roll I20 has a similar central shaftI32 having its projecting ends arranged to form supporting trunnions.These supporting or trunnion-like ends of the shaft I32 of the forcingroll I25 are supported in similar bearings I33 formed along the upperedge of the side frames I I6 adjacent the left-hand end thereof asherein shown, the bearings I33 being formed and positioned in the samemanner as the bearings 33 of Fig. l. I

The molding roll H is supported on an axis which is at the same heightas the axis of the forcing roll I20, and such support is, in accordancewith the present invention provided by readi-ly separable bearings I35which are formed and positioned in the same manner as the bearings 35shown in Fig. 1, thereby to facilitate the removal and replacement ofthe die roll I I9.

The hopper IZI is formed and mounted in substantially the same manner asthe hopper shown in Figs. 1 to 3, so that it may be readily moved to anout-of-the-way position in the same manner. A similar interlockedbearing means I45 provided on the hopper I2I, which, with similar anglebrackets I41 and clamping studs I49 provides for convenient shifting ofthe hopper I2I as explained in connection with Figs. 1 to 3. In theembodiment of Figs. 6 to 10, however, the hopper has a bottom wall I44which slopes at a rather steep angle to a point beyond the uppermostpoint on the forcing roll I211, thereby to feed the dough moreefficiently into the trough-like space between the two rolls H9 andI211.

The extracting belt I25 is pressed against the die roll II9 by resilientmeans such as a rubber covered roll I56 which is in many instancestermed the extracting roll. This roll I58 is constructed and mounted inthe same general manner as the roll 50 of Figs. 1 to 3, with the ends ofits central shaft I52 in bearing block-s I56 so that the rubber rollopposes the die roll IIQ slightly below a horizontal plane passingthrough the axis of the die roll. The extracting belt is, of course,extend-ed from the nose plate I21 to the left beneath the rubber rollI55 and between the rubber roll and the die roll so as to extend over anelevated tightening or idler roll I55 which is supported above therubber roll and in spaced relation to the die roll. From the idler rollI55 the upper run .of the belt I25 extends to the right over the noseplate I21.

In the embodiment illustrated in Figs. 6 to 10, the rubber roll I55 issupported somewhat lower than in the embodiment of Figs. 1 to 5, whileyet maintaining the lower face of the roll in spaced relation to thesurface I l and the conveyor I3. The rubber roll- I50 is also supportedfor movement toward and away from the die roll I I9 so that the pressureof the rubber roll against the die roll may be adjusted to produce theoptimum extracting action. Such a mounting is attained in substantiallythe same manner as in the other embodiment, the bearing blocks I56 beingsupported on horizontal surfaces I51 formed in the side frames I I6adjacent the right ends thereof. Movement of the bearing block I56 tothe left is limited by an end surface I58, while movement to the rightis limited by vertical end members I59 which are secured by means ofscrews I65 to the right-hand ends of the side frames I I5. 6 to 10, eachbearing block I56 is held down upon the surface I51 by means of a topplate I6I, one end of which is secured to the top of the end member I 59by a hinged connection I52 and the In the embodiment of Figs. 1

other end of which is held down upon the top 'of the side frame II6 tothe left of the face I58 by means of screws 163. With this constructionthe top plates I6I may be readily released by removal of the screwsltl-bwhereupon the top plates sitions so as to facilitate upwardwithdrawal of the rubber roll I50 and its bearing blocks I56.

To press the rubber roll against the die roll, suitable adjusting means.is provided for the blocks I56, and in the present instance thisadjusting means comprises a screw threaded adjusting device I54 for eachbearing block. The adjusting devices I62 of Figs. 6 to 10 areconstructed and mounted in the same manner as the corresponding devicesof Fig. 1, and function in the same manner to force the bearing blocksI56 and the rubber roll I56 to the left in Fig. '1 into the desiredoperative relation to the die roll I I9. When the desired positioning ofthe rubber roll I55 has been determined, this adjustment is preserved inthe embodiment of Figs. 6 to 10 by means of adjustable stop means whichmay be left in any adjusted position even though the adjusting devicesI55 are disturbed. This I61 may be pivoted to out of the way postopmeans as herein shown comprises a pair of stop screws I65, one of whichis threaded through each frame IIB so as to extend beyond the surfaceI58 and toward the left-hand end of the associated bearing block I56.These screws I65 extend through webs I56 which form the end surf-aceI58. Thus when the rubber roll I has been adjusted so as to exert thedesired extracting pressure on the die roll H5, the stop screws I65 aretightened against the left-hand ends of the bearing blocks I55. devices"it may then be disturbed at will, and may be readily re-establishedmerely by forcing the two bearing blocks I back against the stop screwsI65.

The nose plate 21, in accordance with the present invention, is mountedat a fixed spacing with relation to the side frames I15, and the desiredtightening of the belt I25 is attained through movement of the idlerroll I55. The mounting of the nose plate 21 isattained in the presentinstance by means of a pair of arms I15, each of which is fixedpermanently to the nose plate I21. The arms I113 are disposed adjacentto opposite ends of the nose plate I21, and extend to the side frames H5parallel to the side edges of the extracting belt I25. The left-handends of the arms I15 are secured to the inner faces of the side frameslit by pivot pins III which are coaxial. In the form shown in Figs. 6 to10, the nose plate I21 extends outwardly beyond the arms I'lll', so asto overlie the side rails I5, and slots I21 are provided in theseprojecting ends through which fastening bolts I12 may extend intothreaded engagement with the rails I5.

The adjustment of the Thus a predetermined spacing of the nose plate I21with respect to the belt I3 may be established, and this relation willbe independent of and undisturbed by tightening of the belt I25. Thusuniform discharge of the cookies from the belt I25 onto the belt I3 isassured.

The present invention so mounts the idler roll I55 that it may bereadily moved to an out-ofthe-way position when a die roll is to beremoved and this mounting is such as to provide for convenient shiftingof the idler roll I55 to tighten the extracting belt I25. As hereinshown a pair of forked mounting members I12 are provided to engage theprojecting end trunnions I13 of the idler roller I55. Each forkedbearing I12 has a threaded stem I13 which is so mounted that the desiredadjustment of the idler roll 'may be attained.

In the form shown in Figs. 6 to 10, such support is provided byupstanding brackets I14 formed integrally on the top plates IBI. Eachbracket I14 includes a pair of spaced lugs I15 with aligned bores I16formed therein to slidably receive the stems I13. Between the lugs I15 aknurled nut I 11 is threaded on each threaded stem, so that by rotationof the nut I 11, while the bearing shaft I13 of the idler roller I55holds the bearing and its threaded stem against rotation, results in thedesired adjusting movement of the associated forked bearing. In the formshown in Figs. 6 to 10, the threaded stems I 13 are positionedhorizontally, but if desired, an angular positioning might be adoptedapproaching the 30 inclination employed in the other embodiment.

The knife means constructed in accordance with the present invention andembodied in the cooking machine illustrated in Figs. 6 to 10 is' mountedin the space beneath the two rolls H9 and I20. As herein shown, thisknife means is indicated generally at I 89 and comprises a supportingshaft I8I preferably made from a good quality of steel shafting andsupported so as to be positioned immediately below the adjacent edges ofthe two rolls H9 and I28. Such support for the shaft I8I is provided bytwo bosses I82 formed one on the upper face of the bottom rail I83 ofeach side frame II6. Immediately above the boss I82, the center web ofthe side frame H6 is recessed or cut away as at I84.

The shaft I8I extends at its opposite ends through aligned bores I85formed in the two bosses I82, and intermediate these two points ofsupport, the shaft I8I carries a knife holder I86. This knife holder I96may be in the form of a casting having bearing lugs I81 at its oppositeends embracing the shaft I8I. At spaced points intermediate the bearinglugs I81 the knife holder I86 preferably has arcuately formed bearingpads I 88 which rest against the upper surface of the shaft I8I. On asurface E89 of the knife holder I 86, a knife I98 is secured as by meansof a plurality of screws I9I and preferably the lower edge of the knifeI99 rests against an upwardly facing shoulder or surface I92 formed onthe knife holder. The knife I is so proportioned that its upper edge I93may be shifted to the right in Fig. 9 so as to engage the outer surfaceof the die roll II9 slightly below a horizontal plane passing throughthe axis of the die roll, and the knife normally urged into suchengagement by spring means. This spring means, in accordance with thepresent invention, comprises a pair of expansive coiled springs I95which surround the guide rods I99 mounted in the side frames II6 asshown in Fig. 9. 'Each guide rod I96 is mounted in an end web I91 of itsside frame II6 so as to act between the associated web I91 and an armI98 which projects endwise from the adjacent end of the knife holderI86. Each guide rod I96 extends through its arm I98 so as to besupported thereby, and hence the springs act under all conditions toyieldingly urge the knife I98 into operative engagement with the dieroll H9.

The guide rods I96 also are utilized in the present instance to providemeans acting as stops to limit the clockwise movement of the knife (Fig.9) when the die roll H9 is removed. Thus guide rods I96 have heads I99thereon, located on the right-hand side of the arms I 98 so as to limitthe movement of the knife by the springs I95. Preferably the heads I99are of non-circular form and fit in complemental sockets in the armsI98, so that by means of nuts 200 threaded on the left-hand ends of therods I96, the range of movement of the knife by its springs I95 may beadjusted and varied.

Since the supporting shaft I8I may be made of a relatively high qualitysteel, and since this shaft is positioned along the lower edge of theknife holder I86 with several spaced points of supporting engagementwith the knife holder, it will be apparent that the hammer-like blows,that are applied to the knife and to the knife holder when defects arepresent in the surface of the die roll II9, will be resisted in such amanner as to prevent cracking and breaking of the knife holder. Suchbreaking of the knife holder has heretofore been quite common and by thepresent construction it will be evident that the loss of machine oroperating time due to such breakage will be substantially eliminated.

By mounting both the die roll and the rubber roll so that theirseparable bearings open upwardly from the exposed top edge of the sideframes, the present machine is rendered highly practical and convenientin use. The removal of the die roll may, of course, be easilyaccomplished, and in addition, the rubber roll may be readily taken outfor mounting of a new extraction belt on the machine.

The mounting of the rubber roll so that a substantial part of its endsurface is exposed is of great importance, since it enables the user topreserve the rubber roll for a length of time heretofore not attainable.This important result is attained by reason of the fact that the usermay frequently wipe the grease or shortening from the end surface of theroll, and thereby prevent this grease from working into the annularjoint between the rubber sleeve and its core. Such grease is expressedfrom the cooky dough in the normal use of the machine, and while therubber sleeve may in itself be made from a grease resistant rubber, ithas been impossible to produce a grease resistant joint between therubber sleeve and the steel core. I have discovered that such greaseworks into the joint between the sleeve and the core, and in actualpractice gradually loosens the sleeve from the core. As this looseningpro gresses, the cookies adjacent the ends of the die roll are notextracted properly. I have further discovered that by wiping this greasefrom the ends of the rubber roll at frequent intervals, properextraction of the cookies may be attained for a much longer period witha given rubber roll.

When a machine of this character is in operation, the extracting belt,by uneven stretching or for other reasons, often tends to run with abias or camber so as to move to the right or left on its guide rollerand nose plate, and heretofore, such bias running of the belt wascorrected solely by .adjustment of the nose plate. This nose plateadjustment was also used to tighten the extracting belt; and in manyinstances the required adjustment was such as to displacethe nose platefrom its desired right angle relation to the conveyor path, and inaddition, often tended to disrupt the desired relation of the cockydischarge line to the pan positioning on a pan conveyor.

By the present construction the nose plate remains, in a functionalsense, substantially stationary with respect to the conveyor, and therequired adjustment is attained by means of the idler roller 55, therebyto avoid the objectionable results of the prior nose plate type ofadjustment. In addition, this adjustment is made adjacent to the pointof extraction, so that the effect of the adjustment on the extractionmay be carefully observed as the adjustment progresses.

The mounting of the hopper in the present case is such as to assureproper positioning of the hopper with relation to the forcing andmolding rolls when the hopper is in its normal upright position; and inaddition, the hopper is guided and supported in its movement to and fromits out-of-the-way position, thereby to facilitate this operation andgive assurance that the die roll will not be injured in the manipulationof the hopper. The shifting movement of the hopper being so guided, maybe said to have a rocking movement to and from its out-of-the-wayposition.

After the hopper has been rocked to its out-ofthe-way position, the beltreleased, and the idler roller removed from its bearings, the removal ofthe die roll from its opened bearings is extremely simple in the presentmachine. This simplicity results in a large measure from the point orline of engagement of the rubber roll with the die roll. This line ofengagement is slightly below the horizontal plane passing through theaxis of the die roll bearings, so that the die roll may in effect berolled upwardly and to the right (Fig. 1) along the surface of therubber roll. In such rolling movement it will be noted that the angle ofthe separation of the bearing 35 has an important relation, for it isclear that in such rolling movement of the die roll along the surface ofthe rubber roll, the trunnion portions 3| of the die roll shaft movefreely out of the lower portions 35' of the bearings 35.

Such rolling relation of the die roll along the rubber roll is also ofgreat importance in mounting the die roll in the machine, since itsimplifies the operation and reduces the effort required to support thedie roll,.and thereby insures against damage to the die roll or itsbearings. The pivot upper sections 35" of the bearings, being located onthe sides of the bearings opposite from the rubber roll, are, of course,out of the way at all times during the changing of the die roll.

By locating the rubber roll on the forward side of the die roll, so asto engage the die roll only slightly below the plane passing through thedie roll axis, the present invention provides a cocky molding machinewhich may use a relatively large rubber roll, and yet have but a smallheight above the discharge level of the extracting belt. Thus the use ofthe machine is simplified. Moreover, the elements are disposed so thatthe present machine may be used as an attachment for mounting on variouscutting machine bases, or on the frame of steel band conveyors. Also thepresent machine may be provided with its own base, either portable orstationary, so that the present molding structure may be used in a largevariety of ways.

The rubber roll mounting of the present machine is of particularadvantage as compared with prior machines, in that the bearing blocks 58are mounted directly upon the heavy side frames l6, and the weight ofthe rubber roll is supported directly by the surface 51 rather than upona rocking carrier or vertical feed screw as heretofore. Thus the onlyforce placed upon the adjusting devices 54 is the pressure actingbetween the rubber roll 56 and the die roll l9, and any upward ordownward force is taken by the relatively heavy cap plate 6! or thebearing surface 5'! of the frame It. Consequently the alignment andadjustment of the rubber roll in the present machine are attained andpreserved much more effectually than has heretofore been possible.

In enabling the user to preserve the alignment of the various operatingparts of the machine, the hopper construction of the present machine isunique, for it will be evident that when the hopper 2! is in itsretracted position of Fig. 1, it may be lifted upwardly and easilyremoved from the machine without disturbing the alignment or mounting ofany ofthe other parts of the machine. quired for the inspection orrepair of the other parts of the machine.

In maintaining and assuring proper operation of the machine, therelative positioning of the rubber roll and the axi of the die roll, andthe form and inter-relation of the bearings 35 are of particularimportance. This importance becomes clear by comparison with priormachines wherein the force applied by the rubber roll Was taken solelyby the removable section or cap of the die roll bearing. This action wasdue to the mounting of the rubber r011 beneath the die roll so that itpressed upwardly on the die roll. In the present machine it will benoted that the line of application of the force to the die roll by therubber roll is such that this force acts on a portion of the fixedsection 35 of the hearing 35. Moreover, this force applied by the rubberroll is in its principal component, directly opposed to the reactiveforce between the die roll and the forcing roll, with the result thatthe wear producing forces on the bearing 35 are relatively I small.Hence the present machine causes less difficulty in practical use, andreduces the idle time heretofore required for repairs and the purview ofthe following claims.
